2.3. Issues and mitigation

Issue Description

Mitigation Description

Issue description

Issue mitigation

CSCS Internal network

Found some network problems on the Infiniband fabric. At times the

Subnet Manager would incorrectly failover to a SM on a switch. We fixed it
by forcing two hosts to hold our SM with higher priority than the switches.

UNIBE ARC Versioning

Ambiguity in versioning and production requirements between Nordugrid, UMD and EMI has caused unsolved problems in the deployment of a new cluster fronted by an ARC CE

UNIGE WN

One of the new worker nodes is not stable under SLC5.

Mitigation: Bios upgrade and reinstallation. We don't know yet if it helped.

UNIGE DPM/BDII

Previous site BDII, which was also the resource BDII for

the DPM SE, had to be reconfigured to be only the resource BDII and stop
being the site BDII.
Mitigation: The software had to be hacked. Expert help was needed.

UNIGE DPM

The DPM software is no longer supported for the Solaris OS.

We still have six Solaris disk servers in our SE, representing 1/3 of the space.
Mitigation: Don't upgrade the software on the disk servers. Replace the
disk servers at the next hardware upgrade, hopefully in Autumn 2013.
